I noticed other threads complained about lack of CHANGELOG for firmware updates. I don't know what they have that they think is so secret, that thry can't tell us what bugs were fixed. As an engineer I dislike this lack of transparency. On the other hand these headphones mostly just work, apart from a few annoyance with reconnect time, etc.
